This
new non-linear crystal Cesium Lithium Borate (CsLiB6O10
or CLBO) suits well for UV applications and generates the
4th and 5th harmonics of the Nd:YAG fundamental laser wavelength.
CLBO is transparent down to 190 nm and can be phase matched for type-II
SHG to 640 nm and type-I to 477 nm. CLBO is more readily grown than
BBO as it melts congruently and it can be grown directly from the
melt which eliminates the scatter seen in BBO due to the flux inclusions.
CLBO has excellent non-linear optical properties - larger angular
and spectral bandwidths than BBO. It also has a lower deff
than BBO, but a smaller walk-off angle and high damage threshold:
26 GW/cm2, twice that of BBO. We supply as-cut blanks,
as well as optical elements made according to customer's order.
